Specification of Letters Patent.

latented Apr. 13, 1920.

Application filed February 15, 1919. Serial No. 277,299.

1 b all whom it may concern Be it known that I, CHRISTINE DAVIS, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Thread-Holder, of which the following is a specification.

This invention relates to improvements in thread holders for spools, the primary ob- 'ject being to provide simple and inexpen sive means for holding the loose end of a thread on a spool to prevent unintentional unwinding.

With this and other objects in view my invention comprises the features of construction and combination of parts hereinafter more particularly described and claimed.

in the drawing, Figure 1 is a vertical sec tion of an ordinary spool of thread and of my invention applied thereto; Fig. 2 is a perspective view of my improved thread holder removed from the spool; Fig. 3 is a vertical section of a spool of thread showing an alternative construction of my invention applied thereto, and Fig. 4 is a perspective of the thread holder made in ac cordance with the construction shown in Fig. 3.

In the drawing let A indicate an ordinary spool having a thread C, wound thereon and the usual central longitudinal hole B. My invention comprises a single flat strip of thin metal 2 tapering in width toward one of its ends, the broad end of said strip terminating in a body 3 resem bling a split cylinder arranged with its axis right angles to the strip or body of mate rial 2. Tlv e cylindrical portion of the device is adapted to be inserted in the hole B in the spool leaving the fiat body of the strip 2 lying against an end and radiating out wardly from the axis of the spool. The outer free end of the strip 2 is bent down wardly and upwardly into the form of a hook 5, the sides of which are pinched together at 12 to form a catch which will hold the free end of the thread C when inserted firmly deep between said sides. The device can be swung around the aXis of the spool when desired to adjust it into any position required for securing the free end of the thread. Vvlhen the free end of the thread is caught and held by the hook 5, the friction of the body 3 due to the tendency of the curved end portions 6 and 7 expanding holds the device rigidly in selected position on the spool.

In the construction illustrated in Figs. 3 and 4c, the invention is constructed out of a single piece of wire shaped with a body 8, which is substantially U shaped to be inserted in the hole of the spool, said body being expansive as in the construction illustrated in Fig.2, whereby it will frictionally engage the spool in the hole and tend to prevent the holder from moving after it has been adjusted in position. The body 8 likewise is provided with an arm 9 radiating outwardly from the axis of the spool over the end, said body being turned inwardly and formed with an overhanging arm 10, which is provided with a thread engaging hook 11 on its extremity.

Having described my invention what I claim as new and desire to protect by Letters Patent is:

A thread holder for spools having a short spring body adapted to be inserted a short distance in an end of the hole of a spool, and to expansively engage the spool. said body being formed with an arm radiating outwardly closely over an end of the spool said arm being formed with an overhanging end resting on the periphery extending sub stantially parallel with the axis and in wardly between the ends of the spool, the inner extremity of said overhanging end being formed with an out turned hook, the side edges of said hook being pinched in near its base to form a thread engagement.

In testimony whereof I have signed my name to this specification.

CHRISTINE DAVIS.
